ELECTRIC GAS-LIGHTER.

SPECIFICATION forming part of 7 Letters Patent No. 417,075, dated December 10, 1889.

Application filed May 29, 1889. Serial No. 312,652. (No model.)

To all wiwnt it may concern.-

Beit known that I, NELsoN NEWMAN, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have in vented certain new and useful Improvements in Electric Gas Lighters and Extinguishers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the let ters and figures of reference marked thereon, which form a part of this specification.

- My invention relates to an improvement in electric gas lighters and extinguishers; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of an apparatus embodying my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a top plan view of the same. Fig. I is partly a sectional view and partly an elevation, on an enlarged scale, of the valve wit-h its shaft and tappet-arms.

On the base A is supported a rectangular box or case B, of suitable size, and which incloses a suitable electric battery or other source of electricity. (Not shown.) I prefer to employ what is known in the art as a dry battery, but any suitable variety of battery may be used. A case O is also arranged on the base and at a suitable distance from one end of the battery-case. In this case 0 is a suitable clock-work mechanism or other 1110- tor (not shown) having the shaft 0 projecting through its front side, and the said shaft is adapted to revolve once in twenty-four hours. I prefer to employ a clock mechanism which will continue to operate for sixteen days after being wound up; but this is not essential and may be varied at pleasure.

Secured to the outer end of the shaft 0, and revolving therewith, is a circular disk or dial D, of suitable size. The said disk is provided near its center and at a suitable distance from its perimeter with series of openings a h, respectively.

The said series of openings are arranged in concentric circles, are each twenty-four in number, corresponding to the hours of the day, and are numbered consecutively from 1 to 24, as shown. The numbers of the said series of openings may be varied, if preferred, to suit the exact requirements of each case. Near the perimeter of the disk is a third series of openings (Z. A tappet-pin a. is adapted to be insertedin either of the openings in series a and to project from the rear side of the disk. A similar pin 1) is adapted to be inserted in either of the openings in series b, and a tappet-pin (Z is adapted to be inserted in the openings (1. The gas-pipe E extends through the base and is arranged between the opposing ends of the battery and clock-work cases, and to the upper end of the said pipe is secured the burner F, which may be of any of the well-known forms. A valve G, which is tapered in form, is journaled in a tapered seat, which is arranged at right angles to the pipe and extends across the bore thereof. Near the ends of the valve are made circumferential grooves 7L2, with which communicate openings g in the bearings of the valveseat. A shaft. H projects from one end of the valve, and to the outer end of the said shaft are attached a pair of tappet-arms h h, of unequal length, and which extend in diametrically-opposite directions. The longer arm 71' is adapted to be engaged by the pin a in the series of openings a, and the shorter arm h is adapted to be ei'igaged by the pin 1) in the series of openings Z). A plate L is secured on the upper sides of the cases 13 U, is circular in form, and has a central opening through which the burnerprojccts. A standard M, made of electric conducting material, rises from the plate, and to the upper end of the said standard is attached a contact-arm O, the inner end of which is made in the form of a coiled spring, and thereby the said arm is rendered resilient and capable of yielding to pressure. The

said arm is arranged in a horizontal position 9 and extends to a point at a slight distance above the burner, and is curved or arc-shaped in the direction of its length, as shown in Fig. 3. Arock-shaftJ is mounted in suitable bearings on the plate L, has its inner end upturned to form a contact-arm e, which is adapted to engage the contact-arm O, and has its outer end bent downward at right angles to form a tappet-arm. f, which is in the path of the tappet-pin d in the series of openings (Z. A pair of binding-posts K are secured on the case B and connected to the poles of the battery and to the shaft J and standard 1, respectively, by con ducting-wires 7. A standard N rises from the plate L and has its upper end curved to form an arm Z, which serves as a guide for the contact-arm c. A coiled retractile spring it connects said arm 6 to the standard N and serves to normally turn the rock-shaft to such a position that the arm a is out of contact, normally, with the arm 0, and the tappct-armfis normally in the path of the pins (7 d d.

The operation of my invention is as follight the gas at the ninth hour and extinguish the same at the thirteenth hour, the pin a is inserted in the opening 9 of series a, the pin 1) is inserted in the opening 13 of series (2, and the pin (1 is inserted in the three openings of series (I most nearly in line radially with opening 9 of series (L. The clock-work mechanism, being put in motion, revolves the disk D in the direction indicated by the arrow in Fig. 1, and when the required time has elapsed the pin a will engage the longer tappet-arm 7t and turn the valve a sulficient distance to cause a flow of gas from the burner. The pin cl in the series of openings d at the same instant engages the tappet-arm f of the rock-shaft J, and in moving past the said tappet-a-rm causes the rockshaft to partly revolve against the energy of the spring a and move the arm 0 into contact with the spring contact-arm O, and, owing to the curved form of the latter and the resilience thereof, effecting a sliding contact therewith and closing the electric circuit. lVhen thepin d moves past the arm f, the spring a restores the arm 6 to its normal position and detaches it suddenly from the contact-arm 0, thereby producing an electric spark, which ignites the gas, as will be readily understood. \Vhen the hours intervening between the ninth and the thirteenth have elapsed, the pin Z) in opening 13 of series Z) will engage the shorter arm 7r of the valve shaft or stem, and in moving past the said arm will turn the valve a suiticient distance to cut off the flow of gas through the burner and thereby extinguish the light.

As long as the motor or clock-work mechanism continues to operate, and while the adjustment above described is preserved, the gas will be lighted at the ninth hour and ing apparatus having the operating lever or regularly extinguished at the thirteenth hour automatically and absolutely without the necessity of any attention other than to keep the battery and the motor at work.

The value and utility of a gas lighting and extinguishing apparatus such as described herein will be apparent.

The openings g and grooves it serve to admit oil to the valve to keep the same lubricated and adapt it to be readily operated by the clock mechanism.

Having thus described my invention, I claim 1. The combination of the time mechanism having the moving tappets, the gas-valve having the tappet-arms, and the electric sparkarin also adapted to be operated by the tap- 1 pets, substantially as described. I V V T lows. We will assume that it is required to The electric spark-producing apparatus comprising the curved yielding arm 0, the

contacting-arm c, to engage the same, and the spring to normally move the arm c from the arm 0, in combination with the time mechanism having the moving tappets to operate the contacting arm, substantially as described.

The time mechanism having the revolving disk provided with the concentric series of openings a b d, the adjustable tappets a l) d, in said openings, respectively, the gasvalve having the tappet-arms in the paths of the tappets ct I), and the electric spark-producing apparatus having the lever or arm in the path of the tappet (7/, all in combination, substantially as described.

t. The time mechanism having the revolving disk provided with the tappets arranged at dilterent distances from its center, in combination with the gas-valve having the tappet-arms extending in opposite directions and arranged in the paths of the respective tappets, whereby the valve will be automatically opened and closed and the electric spark-producing apparatus operated by the time mechanism, substantially as described.

5. The time mechanism having the moving tappets, in combination with the electric sparking apparatus having the spring pressed contacting-arm c, and the lover or arm .f, to operate said contacting-arm, and arranged in the path of the tappets, substantially as described.

In testimony whereof I attix my signature in presence of two witnesses.
